Video Port Control Registers

Table 2–9. Video Port Interrupt Status Register (VPIS) Field Descriptions (Continued)

Bit	field	symval	Value	Description
13	DCMP			Display complete. Indicates that the entire frame has been driven
				out of the port. The DMA complete interrupt can be used to
				determine when the last data has been transferred from memory to
				the FIFO.
				DCMP is set after displaying an entire field or frame (when F1D,
				F2D or FRMD in VDSTAT are set) depending on the CON,
				FRAME, DF1, and DF2 control bits in VDCTL.
		NONE	0	No interrupt is detected.
		CLEAR	1	Interrupt is detected. Bit is cleared.

12	DUND			Display underrun. Indicates that the display FIFO ran out of data.
		NONE	0	No interrupt is detected.
		CLEAR	1	Interrupt is detected. Bit is cleared.

11	TICK			System time clock tick interrupt detected bit.
				BT.656, Y/C capture mode or raw data mode – Not used.
				TSI capture mode –TICK is set when the TCKEN bit in TSICTL is
				set and the desired number of system time clock ticks has
				occurred as programmed in TSITICKS.
		NONE	0	No interrupt is detected.
		CLEAR	1	Interrupt is detected. Bit is cleared.

10	STC			System time clock interrupt detected bit.
				BT.656, Y/C capture mode or raw data mode – Not used.
				TSI capture mode – STC is set when the system time clock
				reaches an absolute time as programmed in TSISTCMPL and
				TSISTCMPM registers and the STEN bit in TSICTL is set.
		NONE	0	No interrupt is detected.
		CLEAR	1	Interrupt is detected. Bit is cleared.

9–8	Reserved	–	0	Reserved. The reserved bit location is always read as 0. A value
				written to this field has no effect.

TMS320C64x DSP specifications

The TMS320C64x DSP family from Texas Instruments represents a significant milestone in the realm of digital signal processing. Launched as part of the C6000 series, the C64x DSPs are designed for high-performance applications requiring intensive computational capabilities, such as telecommunications, audio processing, video processing, and industrial control systems.

One of the standout features of the TMS320C64x DSP is its VLIW (Very Long Instruction Word) architecture, which allows for an exceptionally high level of parallelism. This architecture enables multiple instructions to be executed simultaneously, boosting the overall throughput and allowing for complex data processing tasks to be completed more quickly than with conventional DSPs.

The C64x DSPs also boast an impressive clock frequency range, typically up to 1 GHz, delivering substantial computational power for real-time processing goals. Additionally, these processors feature extensive on-chip memory, including L1 and L2 cache, which significantly enhances data access speeds and helps reduce bottlenecks during high-demand processing tasks.

Another key characteristic of the TMS320C64x family is its support for advanced instruction sets optimized for specific applications. These include SIMD (Single Instruction, Multiple Data) capabilities, allowing for efficient handling of large datasets often involved in multimedia processing or complex signal manipulation.

For connectivity, these DSPs often integrate advanced interfaces such as EMIF (External Memory Interface) and McBSP (Multichannel Buffered Serial Port), facilitating seamless interaction with a variety of peripheral devices. This ensures that the DSP can suit different application needs and integrate well into various system architectures.

Texas Instruments emphasizes low power consumption with the C64x DSPs, making them ideal for portable or energy-sensitive applications. Advanced power management techniques and technologies, such as dynamic voltage and frequency scaling, are incorporated to further enhance energy efficiency without compromising performance.

In summary, the Texas Instruments TMS320C64x DSP family stands out due to its high-performance capabilities driven by a VLIW architecture, high clock speeds, extensive memory options, a rich instruction set, and advanced connectivity features, all while maintaining power efficiency. These characteristics make it an exceptional choice for developers looking to integrate robust digital signal processing into their applications, whether in telecommunications, audio and video processing, or embedded control systems.
